PAS for OpenEdge Tomcat-level and application-level log files have the ability to rollover as specified in the fileName property in the logging-tomcat.properties and logging-pasoe.properties files in the /conf directory of the instance.

The log files defined in logging-tomcat.properties and logging-pasoe.properties adhere to the Logback framework. By default, the log fileNames definition includes %d{yyyy-MM-dd}, which indicates the log file rolls over at the start of each day. Log file rollover means the component of the instance stops writing to one log file and begins writing to a new log file.

The PAS for OpenEdge ABL application agent log file (abl_app.agent.{yyyy-mm-dd}.log) uses the OpenEdge Logger framework, rather than the Logback framework. The ABL agent log filename and path is specified in the agentLogFile property in instance-name/conf/openedge.properties.

The ability for the ABL application agent log to rollover depends on the inclusion of {yyyy-mm-dd} in the agentLogFile definition, for example:
agentLogFile=${catalina.base}/logs/oepas1.agent.{yyyy-mm-dd}.log
To stop ABL application agent log rollover, omit the date stamp in the log filename definition, for example: 
agentLogFile=${catalina.base}/logs/oepas1.agent.log
